We divide 349952 by 9
The aim is to understand the frequency of 9 in 349952.

Let's proceed to step 1:
The number 9 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 9

Moving on to step 2:
If we divide 34 by 9, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 27 from 34 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 9

Let's proceed to step 3:
9 goes into 79 8 times with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we subtract 72 from 79, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 9

Going ahead to step 4:
9 can be fit into 79 8 times, resulting in a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 388.0
The remainder is 7 after subtracting 72 from 79.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 9

Step 5:
9 can be fit into 75 8 times, resulting in a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 3888.0
If we subtract 72 from 75, we get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 9

Moving on to step 6:
32 divided by 9 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 38883.0
If we subtract 27 from 32, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
9 can be fit into 50 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 38883.5
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
50 divided by 9 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 38883.55
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 38883.55 with a remainder of 0.005.
